Add OpEndIT() for marking the end of OpIT blocks

In ARM we need to prevent code motion to the inside of an
IT block.  This was done using a GenBarrier() to mark the end, but
it wasn't obvious that this is what was happening.  This CL adds
an explicit OpEndIT() that takes the LIR of the OpIT for future
checks.
